Evan-animan: AND JOHN M. LnvIsfoF'cHIoAGo, ILLINOIS, AssIGNOBs 'T o', KImuiLu GLASS COMPANY, orcmcaeo, ILLINOIS, .e CORPORATION OF ILLINOIS.l

Be it known that we, EvAN E.' KIMBLE and JOHN M. LEVIS, both citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have jointly invented certain newv and useful Imi -proVements in Vial-Necking Machines', of

which the lfollowing is a specicatiOn.4

Our 'invention pertains to improvements in machines for automaticallyproviding on thek ends of glass tube sections shoulders, necks, and lips, whereby, after both ends of such sections have been thus necked, they may be divided latthe center and their two parts-closed to form independent vials.

There ire several features of our machine having marked advantages over those of the prior art, and among such we may mention the employmentof meansto primarily lor. initially vheat the ends of the glass tube sections while they are on the carrier or conveyer and Abefore they reach the position where they are acted upon by the main heaters and neck-forming fols.-y By the use I -paring them, without loss of time, for the` of such a contrivance e fare enabled to produce `vials with vc nsiderable rapidity, the` preliminary heating of the blanks premain heaters and tools. We have also found that in a device of this kind it is highly desirable, if not-quite necessary', that with thev accompanying drawings` forming a part of this specification, and throughout the variousl views of whichy like reference characters refer to the same parts.

In' these drawings-Figure lis a plan inner end of the sha fragments of certain lparts f only ybeing shown; Fig. 4 is a vertical section on line 4 4 of Fig. 2; Fig. 5 isa vertical section Online 5of Fig-2 illustrating one ofthe actuating cams; Fig. 6 is a horizontal section on an enlarged scale; Fi ..7 a Vvertical section on lme 7--7 of i 3, vcertain f. parts being omitted for the sa e of .clear- Patented Nov. 2 1, 1.911."

e ming as the-drawings, va will be 2, 3 and/), and is supplled at its ltop'with f a ilat horiontal enlargement 21-provided with apertures extended v' `longitudinally therethrough for three round shafts or.- rods 22,` 23, and 24I arranged side by side, as is clearlyindicated n- Figs. 1 2 and 6. The 22`i's'isupplied with toolportion 25. adapted to blanlrtoibe acted upon and 'to an inner` flat. enter the tube .determine the interior \`caliber orf diametei` of the finished neck, tlis'ixgol having a square enlargement 26"`iv5rith aiiat face or shoulder 2'( adapted brought against' ad i the end of the heated tube section to form the mouth ofthe bottle and true its outer face. The outer 'end of shaft or rod 22 is slotted to accommodate the upper end of a lever 28 loosely fuicrumed on an end shaft 29 suitably sup'ported inbrackets or bear'- ings 30, thelower end of the lever being equipped with a roller 31 on one side,travel ing in a cam slot 32 provided in the face of a cam 33 fixed to turn with the cam shaft 34 on which it is mounted. y

The middle reciprocatory shaft 23 at its inner end is supplied with a block 35 through which passes a hinge-pin 36, shown in dotted lines in Fig. 12, protruding from opposite sides of the block, and on such pin we fulcrum the pair of jaws 37, 38'oii'set laterally on one side of the shaft 23, such olf-set portion bein equipped wit-h the in serted external nec -forming dies or tools 39 (Fig. 9).v The rear ends of these jaws or arms are off-set on -the other side of the shaft 23,and each is supplied with a roller '40, the two-rollers co-actmgwith the top and bottom surfaces of the third rod or shaft 24, the inner end of which 41 is of wedge shape, as is clearl vshown for example in Fig. 9. The jaws 3 and 38 are normally pressed to Vclosed position by a spring 43 encircling a screw 42 threaded into the upper jaw and loosely passing through the lower one, such spring pressing against the latter and a nut on the lower end of the screw. Turning of such screw adjusts or varies the action ofthe spring on the jaws. The closing of such jaws is limited and restricted by a screwthreaded adjustable stop 44 extending through one of the jaws and adapted to coact with a fixed stop or abutment 45 on the other jaw. A slot is provided in the outer end of shaft 23 .to accommodate the top end of a lever 46 mounted to rock on, the shaft 29,'as is the lever 28, and likewise supplied at its lower end with a roller 47 traveling in a cam groove v48 (Fig. 5) of a cam 49 similarly fixed to rotate with the cam shaft 34.. Thexremaining shaft 24 is likewise operatively 'connected to a cam 50 on shaft 34 by a rocking lever 51 loscillatory-0n the shaft 29, this lever, as in the previous instances, being equipped with a roller workingin a cam slot 53 of the cam 50.

The shaft 34 is driven from a lower back l driving shaft 54 (Fig. 3), rotatable in bearings G2 and 63, by means of meshinr bevel pinions 55 and 56, the former being Xed to shaft 34, while the latter isfixed to shaft 54. Also keyed to shaft 54 beside hub 57 of gear 56 is a spur-gear 58, the teeth of which mesh with those of a-pinion 59 on a jack-shaft 60 rotatable in bearing 60a, the other end of such shaft having lixed thereto a gear wheel 61 meshing with apinion 64, forming part of a 'clutch sleeve 65 loose on shaft 54 and slidable ,thereon to render the clutch 66, inside ofthe driving pulley 67 also loose on shaft 54, op-y erative or inoperative. Clutch sleeve is operated by one or more oscillatory `arms 68 on a small rock shaft 69pt() which is connected an actuating or controlling handle 70, shown in dotted lines in Fig.' 3. Ob-' viouslyA shafts 34 and 54 rotate at a much less speed than pulley 67.

Two main suitably-supported heating appliances 7l and 72 (Fig. 6) are employed at the front and back of the machine and are so arranged that the blow, pipe blasts of burning gas and air will be directed on to the end of the tube section when in position to be acted upon by the internal and external neck-forming tools described above. The two heaters 71 and 72 are each supplied with a plurality .of gas burners or tips 73 each having a considerable number of perforations for the escape of the gas, which is conducted to the individual burners by the -valved gas pipes 74, 74, connected, respectively, to the gas pipes V75 and 76 by means of apertures in the parts 77 and 7 8 of the main frame. These two pipes, by means of a single short connecting pipe 79 (Fig. 3)., are brought into communication by a gas valve 80, connected at its upper end to a main gas supply pipe 81. Asis clearly inv dicated, the arm 82 of this gas valve is normally pulled downwardly-by a coil contractile spring 83, and is connected by a llnk 84 to the outer end of acam arm 85 suitably fulcrumed on the frame at 86 and supplied with a nger or projection. 87, which co-acts with the cam 88 on the outer `surface of the shaft controlling cam 50 the gas will be almost entirely shut off, per-I mitting a suiiicient flow to the burners, however, to j prevent extinguishment of the flames.

Each of the gas burners 73 has associated therewith a compressed air pipe 89 (Fig. 6), each terminating in a'nozzle 90 at the end of its burner, whereby the jetof air issuing ,therefrom will supply oxygen for the complete combustion of the gas, and will direct or blow the flame on to the end of the tube to be operated upon. The three air pipes 89 atrthe front of the machine are each supplied with a valve 91 and are all connected to a single air supply pipe 92,

while the corresponding air pipes at the noname lower end'of `which is connected by a" pipe 9'6 with "an `suitable `source 4of compressed air supp y.

Asin the case of thev gas valve, the arm 97-of this air valve is normal1y.spring-pulleddown, and by means fio of a 'link 98 isconnectedto a rock. arm 99, similar .tothe a1'm`85, andsupplied with a projection 100 on its under surface, co-actfing with aca-m -10'1 on thefexterior surface yof the cam 49. lt'wilhtherefore, be apparent that the rotation of'this cam'lOl will control t-he lopening and closing ffthe comy'pressed air v.valve 95 and the flowing air to the burners.

The4 preliminary heater.- .or gasv burner 102,shownin full-lines in Fig. 7 and indotted lines below. the front burner 71 6, comprises nothing more. than an. ordinary Bunsen burner mounted on a rod 103 projecting' lengthwise the machine from the main frame, and supplied with .gas through .a pipe 104Jconnected to the apertured block i 77, and furnished withair through a pipe 105 connected to van airvsupplypipe 106, which also conducts compressed air through the pipe 107 (Fig. 6) to a discharge blower or nozzle 108 adapted tofdirect a jetI or blastv of air against the neck-forming tools 'and-shafts described above to e061 them at intervals if vfoundio be necessary, the supply of air passing through the pipe 107 being controlled by a 'valve 109 inserted therein. n y Referring to Figs. 3, 6 and 7, it will be noticed that 'on the outstanding rod 103 and a similar rod 110 we mount a Ypair of plates or supporting' members 111 and 112 cenf trally apertured and of irregular shape, which may be traced on Fig. 7. In suitable bearings on ythese two spaced plates and at 'their` top" portions we mount two shafts 113 ',and'114 (Fig. 6) each suppliedwith ya plurality of rollers 115 adapted to support the tube section while it is being acted upon by the main heaters and neck-forming tools de- Somewhat removed from these shafts androllers toward'the front of theinachine andalso mounted on Aplates 111 and' 112, we supply a shaft 116 havingon its ends similar rollers 117 onwhich the tubes .are adapted toA rest while being acted upon by lthe preliminary heater 102,l the position "of `these rollersjbeing -indieated in dotted lines iniFig. .7. Atube carrier orconveyer 'is'l'oose'ly mounted ona'n outwardly-extended studshaft 118` (Fig.'4),-the inner end of .which is supported in an aperturedboss 119 forming part. of themachine frame, this car- ,rierocomprismg'a pair of notched wheels 120and 121fixed .to a sleeve 122 rptatable "on ,the supportingshaft 1'18'andfheld in 111399.); byf ytf. @9115117.12231 A .A150 fx l0 this. sleeve and rtatablefwithjjthe e c Trier" we 7, p .pitvidea'ratchet lwheel124 (Figa 4 and 7 oa with 'a' cylindrical hub i2 loosely mounted .the inner end of an oscillatory armn 126, the lower end ofuwhich, as well as the pawl 127. coe-acting withl the ratchet, isreceived between andy is pivoted to the'v upper b'ifurcated'end 128 of apcam arm v129,a suitable pivot-pin 130, passing through all theparts for'lthe obvious purpose of securingl their pivotal connection.|

The lower end .of arm 129y is forked at131 (Fig. 8), so as to straddl'e shai"t` 54, lthe arm having-mounted on onenside aA roller 132' 139, the' lower end of which is guided hby its fork 131,- and also occasions the forward feedingfof the ratchet and carrier step by step. e n

At. the front side of the machine and Asupported on the pair of plates or'members 111 f.

and 112 arginclined supply ho per 137 (Figs. 1 and'vhavingr apair o parallel inclined bottom supportirig'zbars 137, adapted to contain the tube blanksv anddelive'r them individually to the notched*` carrier,"

-the feeding of more than one ltube at a time .I

to the carrier being prevented by a pair of `curved guards 138 secured tothe inner sides ofthe vertical walls of the hopper, these only one 'layer'of tubes can pass beneath the same. .e l

A `discharge magazine is mounted on the back of the machine and iscoI'Iipo'sedof-a guides or guardsbeing so positioned with relation to the bottom`of.the hopper thatV single vertical plate 139 carried by abracket 140, the latter being supported bythe member 111, as isindicated in Figi?. Also projecting out rearwardly from the two members 111 and 112 are a painof bars 141 and 142 (Figs. 1 and 17) on which thefinished tubes are adapted to roll. To normally bring the tubes against plate '139 the outer bar 142 ,is positioned.V slightly higherthan iio its companion (Fig. 17 To facilitate the p roper discharge of the tubes from the car.- rier, a flat spring v 143 `is mounted on the bracket and`beneath`such spring ,the

ytubes pass as'hey leave the carrier and travel to the tracks or supporting bars 141 and, 142 (Figs. l, 2, 17 and 18). In order .that this deliverycompartment may fill up with. the tubes substantially uniformly, even though they are fed in from the'bottom, the outer ends of bars 141 and' 142 are lcurved upwardlygvas shown in F-ig. 18, and either or both bars are equipped on their top edges Vwith .a slight depressionl or recess 142tto fonwhich is accommodate one of the necked tubes. 1l ,If 13 the number of tubes back of the one in the recesses is small, the tubes as they come into the compartment from under spring 143 will push back the tube in the recess and the others will successively take the place of the former. As the tubes begin to travel up the curved back ends of bars 141 and 142 they will roll down forwardly on top of the others, as shown in Fig. 18, and, if an accumulation of such tubes occurs at the back of the compartment, as shown in such figure, the tube in the recesses 142a for a time thereafter will act to block the backward travel of the incoming tubes, and will act as a wedge to compel such tubes to fill up the front part of the chamber before the remainder of the back'part will fill. Obviously, from such an open delivery compartment or chamber the tubes may be readily removed.

On the stud or shaft 144 projecting outwardly from and su ported by a socket 144 (Figs. l, 3, 4 and 7 we mount anoscillatory skeleton frame 145 carrying a rotary shaft 146 supplied with a pair of friction rollers 147 fixed thereto and adapted to contact with the top Vof a glass tube when it is supported by the rollers 115, whereby rotation of the tube is readily secured. In the present instance the rollers 147 are supplied with rubber tires or peripheralbands 147"` beveled as indicated to rotate the tube and push it back against a rotary stop described hereinafter.

Fig. 16 indicates how as the roller is brought down on to the top of the tube its thin beveled edge is shifted sidewise carrying the tube with it because of the frictional contact between the two. Inasmuch as, during the rotation of the roller, fresh and successive portions of such edge are continually being'pressed out sidewise, the tube is readily maintained endwise against the rotary abutment or stop referred to.

Hinged to the front part of frame 145 on a hinge pin 148 we provide a frame or swinging bearing member 148 caxrying 1e canted or oblique stub shaft 149 supp with a friction roller 150 and a small grooved pulley 151 rotated by a spiral spring belt 1,52 passing around a similar pulley 153 on shaft 146. The. descent of bracket 148a is lim' "ed by its shoulders 148" coming in con- 't t with the front face of frame 145. The

5x5/'rotation of this latter shaftv is effected by means of a .pinion 15.4 (Figs. 2 and 4\ mounted thereon externally of the frame `145 f and having its teeth meshing with those of a gear 155 loose on the shaft 144a and rigidly connected to a sprocket wheel 156, co-acting with which is a sprocket chain 157 passing around sprocket wheel 156 and also around a sprocket wheel 158 fixed to the lower back shaft 54. It should, therefore,'be, perfectly clear vthat t-he rotation of the back shaft `54 shifts the tube blank vtoward and maintains it against a curved guide or stop hereinafter described. In order to raise and lower this rocking frame and the friction rollers carried thereby to permit the glass tubes to be advanced step by step `by the carrier"` the frame 145 (Fig. 7 is equipped with a rearwardly-extended apertured arm 159, through the hole of which extends a Vertical rod 160 supplied at its top end above the arm with a vnut 161 and below the arm with a washer 162, a compression spring 163 being interposed between such washer and the top laterally-bent end of a cam bar 164 forked at its lower end at 155 to straddle the shaft 54 and supplied with a roller 166 operating in' a cam groove 167 in cam 168 rotatable with shaft 54.

In order to properly position the tube sections or blanks in the carrier, and especially during the heating and forming operations, we mount in the top apertured divided or split portion of a bracket 169, mounted on Athe outer end of shaft 118, a cylindrical sup- Aorder to provide effective means for adjustmg such stud in and out of the bracket, that is toward and from the neck-forming tools, the stud is supplied with a threaded eXtension 171c of reduced diametencoperating with 'which is an adjusting nut 171c1 axially threaded to receive a portion of the extension 171e and externally threaded to engage the internal threads 171e at the end portion of the a erture orvhole through the bracket, these twlset-s of threads being of different pitch whereby turning of the nut by .its knurled end 171 will slide or adjust the stud as desired. A curved bracket 171g is lit-ted on the protruding end of the stud 170 and is held in proper positionby a set-screw 1711. The inner end of stud 170 is provided with a recess 171l containing a single ball bearing 171j at its inner end against which is adapty Aed to bear the inner reduced vend 171k of a rotary stop or abutment 1711 positioned in alinement with the tube supported` by the rollers 115. As is indicated, this rotary soA its

:.2155 tube section which has lust rolled out of the abutment1171l isv received. partially. or wholly within the aperture of the curved guide 1718, v its extensin' 171k having a curved annular recess 171nl coperatin with which isa' reg. taining ball 1715- artia ly located a Cavity 'orvhole 171 of -t e stud,suchballretainingthe rotary abutmentfpr stop in position-as' i'ong as the guide 171g isttedove the same to retain the `ball in this recesjs, To remove the lpartsit is necessary first t'o slide oli thejguide, after which 'the ball 17 11W-can be taken 'out and4 the `other 'parts readily re moved, as will be' obvious. Owing'to the `fact that the ends' of these glass blanks possessfconsiderable grinding action-during their rotation, this rotaryl abutment, whichv may behardened if desired, is suppliedr to. preventany grinding or wearing on the -g'urved guide 1718, it being apparent vthat -this stop because of its ball bearing arrange-- 1 ment .is readily rotated, the ball 1 71j taking all of the longitudinal thrust. Since no neck-forming or similar tools are applied to the. blanks during their preliminary heating, rit 1is not necessary ordinarily in a device -of this kindto provide a. rotary 'stop of .this

character opposite the end of the blank when in Lits preliminary heating position. v In order to `facilitate the operation of the tools acting on the heated tubes, we provide the top of the device with an oil tank 1.72 having a discharge pipe 173 from 4which the oil may drip on to the tool 25 adapted to enter-the heated tube, the oil also drip-Y ping, of course, on the reciprocating shaft 22. Belowthis tube and shaft we. place a catch- .basin 17 5 for the recovery of the surplus oil f The operation of this machine is substan-` "tially as. follows :'-Assuining that the sup ply compartment 137 has been furnished with a plurality of glass tube sections of the proper length, such tubes roll down the `inclined bottom bars 137a of the hopper and in a single layer beneath the curved niembersi 138, the tubes individually rolling into a pa'irof alined notches'of the rotary carrier 12d-121. The frame 145 and the friction rollers carried thereby will be lifted at j intervals by caml 168 and the parts connecting the same with the frame, andV during l such raising of the rollers the carrier, through the operation of the ratchet 1.24. and. paw'l127, will `be turned .a definite .L amount by -means of cam v134, bringing the hopper into the notches ofthe carrier around into 'such .position that it temporarily rests i upon the rollers 117, Where its end willre- 'ceivel its preliminary heating from the lburner r102, it being understood that the tube section which had previously occupied this position was simultaneeusly carried far,-

. ther. -along-,tol be acted upon by the neck-V forming toolsu The tubes having been ad. .vanced as indicated, the cam permits thendescending again so that lthe rotation yand 23 l are advanced by their respective the heated tube section during its revolution',

the v` -tubeseiction just heated-to -be advanced so as torest upon the ipllers 115, the frame 145 80 ofthe-frictionrollers 147 is. transmitted to tl tube to effect its revolution. As will-.be readily understood, spring 160 yieldingly maintains the `rcillers in Acontact with the tubes. After the tube sectionin its new position has been heated suiiiciently by the front and rear blowpipes, the supply of gas is nearly shut 01T bythe action of cam 88, a suilicient flow of `gas bein permitted to maintain'vthe burners lighte n At the same time the supply of compressed airis entirely cut oi by the action of cam 101.v At approximatelythe saine timethe two shafts 22 cams, the inner tool 25 entering the heated 95 open mouth of the tube, itbeing understood that the rollers 40 of the tool-.carrying jaws 37 and 38 ride on the top and bottom'- sur-A faces of the shaft 24 during their advance, '10 and just as the rollers reach the wedge'part 41.0f this wedge shaft the latterjs partially retracted from between the rollers, permitting the spring 48 toclose both jawslupon whereb the pair of exte nal tools`-39 form s the nec of the'vial, as is c early: indicated in` 'Fig 9. During this operation the internal caliber of theneck is determined and Amaiiil tained bythe inner tool 25. -The latteris then caused to advanceyfar her into the heated tube `so as to bring .t e 'flatsurface 27 against the end of the tube, -truingthes'aine 'l up and makin'gthle mouth of, the bottle somewhat thicker than the neck pr main portionofthe bdy, as is indicate/din Fig. 10, this inward travel of the-part 26 squeezing the glass somewhat outwardly'into contact witlithe innenfaces of the tools carriedby the?. jaws. The movement .of 'the parts' sog/.120 timed that. after the shoulder, neck'. mouth have been properly formed, will advance, thrusting its wedge portion between the rollers 40, thereby ing the .opening of thejaws'e'zandas' j the withdrawal of the tools 89 from tli'f'tiibet as is indicated in Fig; 11, 'and' afteiljsttsli?. action 'both of' the 'shafts 22 and' 2lfli"e`tra,et

Vcarryingwthe tools away withl them,v` where? upon the carrier., is givenanoth'er"advanced?? step by the pawl and ratchet mechanism and the tube is discharged into the receptacle 139 beneath the spring 143, the tubes rolling down the inclined portions 174 (Fig. 7 o f the pair of supports 111 and 112. Obviously, then, each tube is brought to the position in Which it is acted upon by the neck tools in a highly heated condition, the temperature of the same having been preliminarily raised almost to the melting point by 'the extra burner 102. As soon as a nevsT tube has been brought to forming position, the blow pipes both at the front and back of the machine are again brought into action by the opening of the gas and air valves, the operation above described being then repeated `for each tube.

With a mechanism of this character, the necks, shoulders, and mouths may be formed on one end of the tube sections and then on the other, after which the sections may be divided centrally and closed to form the bottoms of the bottles. Actual demonstration and investigation have shown that the necking operation can be carried on with, considerable rapidity, owing to the preliminary heating, and that bottles or vials of uniform size can be readily produced With but a comparatively small percentage of breakage, it being merely necessary to keep a quantity of tube blanks in the supply hopper and remove the finished articles from the receptacle at the back of the machine, the device being otherwise entirely automatic in its operation. By having separate and individual cams for controlling the actuation of the three shafts or rods 22, 23, and 24, a ready adjustment of such cams can be secured whereby toobtain the nicety of movement required for the successful operation of these parts of the mechanism.

Whereas We have set forth herein with some considerable degree of particularity the structural features of the various element-s of this mechanism, it is to be understood, nevertheless, that the invention is not limited and restricted to the exact and precise construction shown, because the same is susceptible of considerable variation Without departure from the substance and essence of the invention.`

In order that the desired niccty of adjustment may be secured for the tools acting on the tube section necks, We preferably mountI cams 33, 49 and 50 on the shaft 34 so as to be capable of angular adjustment, as, for

instance, the attachment to such shaft may the combination of *a conveyer for glass i tube sections, means to heat the ends of such sections, means to form necks, shoulders and lips on such sections WhileV thus heated, means to preliminarily heat such section ends, a friction roller adapted to contact with and rotate the tube section While acted upon by said forming means, a gage, and asections, means to form necks, shoulders,
